What prop works the best for a 31 AO bravo boat without extension boxes?

almost everyone is running 4 blade bravo's ... if you would like to have less prop slip you can get into a 5 or six blade works well, but beware that when you add blades your prop slip will go down. this also is tougher on the drives and can cause more failure...

My Chris Cat has 3 blade labbed cleavers. Don't know the size, where do i look on them to get the sizes?

not sure, i'm not very familiar with the trs and speed master splines, but if there isn't anything on the outside of the prop it's probably on the end of the prop either up against the drive or the washer and nut.

hydromotive props are faster on the ao's

Wannabe...the SSM pitch and pt# is usually under the washer holding the prop on.

Crap- gotta take it off.

Planning on more HP next year 700 hp 572's.

need bigger props, seems everyone is running 4 blades.
